Answer:
28.7 m at 46.9°
Explanation:
The x component of the displacement is:
x = 6 m cos 0° + 25 m cos 57°
x = 19.6 m
The y component of the displacement is:
y = 6 m sin 0° + 25 m sin 57°
y = 21.0 m
The total displacement is found with Pythagorean theorem:
d = √(x² + y²)
d = 28.7 m
And the direction is found with trig:
θ = tan⁻¹(y/x)
θ = 46.9°
The appropriate response is the negative charge owing fascination of positive charge of the plastic street. Particles are comprised of protons, neutrons, and electrons. Neutrons are unbiased and don't have any charge whatsoever. Protons convey a positive charge, and electrons convey the negative charge. At the point when a question has a positive charge, it has a bigger number of protons than electrons.
Explanation:
The question is incomplete. Here is the complete question.
<em>A toy rocket is launched vertically from ground level (y = 0 m), at time t = 0.0 s. The rocket engine provides constant upward acceleration during the burn phase. At the instant of engine burnout, the rocket has risen to 98 m and acquired a velocity of 30m/s. The rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground. The upward acceleration of the rocket during the burn phase is closest to...</em>
<em></em>
Given
initial velocity of rocket u = 0m/s
final velocity of rocket = 30m/s
Height reached by the rocket = 98m
Required
<em>upward acceleration of the rocket </em>
<em></em>
<em>Using the equation of motion below to get the acceleration a:</em>
<em></em><em></em>
<em></em>
<em>Hence upward acceleration of the rocket during the burn phase is closest to 5m/s²</em>
<em />
<em>Note that the velocity used in calculation was assumed.</em>
The answer for this question is negative externality
$ 376153 is depreciation on the building for 2018.
<u>Explanation:</u>
Given data:
Original cost = $13.1 million
Residual value = $2.1 million
Useful life = 20 -year
Depreciation on the building for 2016 =
By substituting the given values, we get,
= 5500000
Depreciation for 2016 $5500000
Depreciation for 2017 $5500000
Depreciation at Dec 31, 2017 $ 5500000
In 2018, the estimates of useful life and residual value were changed to 15 years and $610000, but 2 yrs have already passed, so there're 13 more yrs to go.
Depreciation on the building for 2018,
=
